Problem
 

How do I equipt items to my character!?

if you mean you have weapons but can't use them in battle, go to the admin control panel > itemshop > edit items > then edit categories. if it's weapons set it to one/two handed weapons, if it's potions set it to potions, etc. and make sure to set the buffs or your weapons won't do any damage, same for items.

hope that helps.

And just for general equipping, they are equipped automatically.
